Part Number: UCC28700-Q1 I am using UCC28700QDBVR-Q1 for designing four isolated output of 12 Vdc & 0.2 A each. Below are design goal parameters
Vin (min)= 250 Vdc
Vin (max)= 400 Vdc
Vout1, Vout2, Vout3, Vout4= 12 Vdc each
Iout1, Iout2, Iout3, Iout4…
Part Number: UCC28700-Q1 Team,
I am helping a customer with worst case analysis and a question came up on the gate current sink spec. Should a gate resistor be used to limit the sink current when the Fet driven is being turned off since the abs max continuous…

Part Number: UCC28700-Q1 Hi,
I used this chip for 12V to 20V flyback. I am not sure if this chip is suitable for this application or not.
To run it, I used another boost converter to supply it VDD to 25V, because the turn on voltage is above 12V. When…

I'm designing a DC-DC converter for automotive application. The maximum input voltage is 420V and output would be 5V. Output current for this application is low. Maximum output…
Part Number: UCC28700-Q1 Hi,
We got a question from customer about UCC28700-Q1. Could you help us?
[Question] They are considering to set any maximum switching frequency. They are thinking it can be setted by equation (21). Is their understanding of this…
Part Number: UCC28700-Q1 Hello,
i need help reviewing the design of the flyback supply with 2 secondary outputs.
Currently i have a problem where the VDD would ramp to around 20V then the device restart itself. I can also hear the audible clicking noise…
